UNITED STATEE ARTHUR J. HARRIS, OF PATERSON, NEW JERSEY.

LOOM.

Application filed. July 1,

This invention relates to looms of the type set forth in the HarrisPatent No. 950,021, for example, in which a device for receiving thefinished goods is driven rotatively from a rotary warp-supply device,whereby to wind up the goods on the receiving device as the warp isunwound from the warpsupply device. In the winding on the re ceivingdevice the practice has been to shift a guide for the goods lengthwiseof the axis of the receiving device from time to time so as to form apackage consisting of a succession of piles in the form of flat coilsarranged side by side. When the goods are very narrow ribbons, andespecially if when narrow they also have relatively thick cord-like edgeportions, such coil-piles frequently have their outer convolutions slipoff laterally, and sometimes an entire coil-pile will collapsecompletely, so that in the finished package the windings are disarrangedand occasionally badly snarled. The object of the present invention isto avoid this difliculty. Instead of forming the package in distinctcoil-piles in which each pile is a coil of the flat type the windingsproceed spirally first in one direction and then in the other around theaxis of the receiving device and this is advantageously accomplished asfollows: Given a revolved receiving device on which to wind the goodsand a guide offset from the axis of winding and around. which the goodsextends to said device, if the winding is effected on said device at apoint remote from a plane perpendicular to the axis and which iscoincident with said guide the winding will tend to progress or traversetoward said plane. In the present invention I utilize this phenomenon toobtain traverse in one direction and to obtain the traverse inthe otherdirection I utilize another guide which at intervals imparts shiftingimpulses in the latter direction.

In the actual construction herein set forth, where the axis of thereceiving device projects rearwardly from the loom, the first guide isarranged in a vertical plane at least as far rearward as the verticalplane of the relatively forward end of the package to be formed and themeans to impart the impulses operates from the latter plane rearwardly.

The invention broadly consists in the combination, with a support and areceiving device iournaled therein and on which to wind the goods, of aguide arranged offset from of said device whisk the supply 1925. SerialNo. 49,799.

goods extends to said device, and means between said guide and device,to impart shifting impulses to the part of the goods between said guideand device substantially lengthwise of said XlS, always in the samedirection and only at one side of a plane perpendicular to said axis andoccupied by the said guide and (in order that the resulting layers ofwindings shall be superimposed on each other) all within the same zone.

In the accompanying drawing, Fig. 1 is a side elevation of a loom,partly 1n section, embodying the invent-ion; and

Fig. 2 is a rear elevation of so much of the loom as includes theinvention, the warpsupply devices being removed.

As in the said Harris patent, 1 is the loom frame, 2 thebreast-beam-carrying glass-bars '3, and 4 the usual beam for supportingglass bars 6. As in said patent each warpdevice 7 and goods-receivingdevice 8 is journaled on a spindle 9 in alinement with the other andthey may be pinned or otherwise interlocked together so as to rotate asa unit. The warp wound on each device 7 is marked 10 and indicated by alight broken line and the woven goods wound on each device 8 is marked11 and indicated by a heavier broken line excepting adjacent said device8 where it is shown-by solid lines. As the weaving proceeds and inconsequence each device 7 rotates under the pull of the warp to deliverthe same it rotates the corresponding device 8 so as to wind up thegoods thereon as set forth in said patent.

W hat I have hereinbefore termed the first guide is afforded in thepresent instance by a transverse beam 12 at theback lower part of theloom; it may be shed with. a metal angle iron 12 to receive the actualcontact of the goods 11. In the present case this guide is arrangedsomewhat forward of the vertical plane with which the forward end ofeach goods package to be formed is coincident so that the tendency ofthe goods is to traverse forwardly in the winding (or in other words toassume the line representing the shortest distance between the guidingpoint 12 and the package) whenever the winding is actually occurringrearward of such forward end.

The mentioned movable guide is afforded by a bar 13 in the present caseforming the top bar of a frame 13 hinged on a horizontal transverse axistothe 12. This frame intervals and then permitted to swing forward againby the following means. On a transverse shaft 1% journaled 011 the frame1 is fixed a cam against which bears frame 13 which may have a roller 16to afford the actual contact; there may be any number of these cams androllers as the length of the frame 13 transversely of the loom mayrequire. A sprocket and chain system 17 is shown to afford means forrotating the shaft lat from any suitable going means in the loom, as therotating take-up shaft 18.

lVhen the loom is operating the cams 15 are constantly rotating. Thesheet of warp and woven goods being held under tension by the weights 19slung in loops formed therein and depending from rollers 20 on the topof the loom frame, the goods maintains the frame 13 against the cams.Consequently, while the winding is proceeding, at spaced intervals thecams act to force the goods rearwardly, thus producing the rearwardtraverse, and in the remaining or alternate intervals they allow thegoods to respond to the tendency to traverse forwardly, the frame beingincidentally held in contact with the cams by the goods during theseintervals.

In this way the wound packages are formed in successive spiralsalternately coiled first from one endL and then from the other end ofthe package, so that the component parts of the package are integratedwith each other and a compact and stable package is produced.

It will be noted that while the shifter 13 yields (when free to do so)to the part of the goods between the guide 12 and the receiving devicein its tendency to assume a plane perpendicular to the axis of saiddevice, it nevertheless is normally urged against said part of thegoods, thereby al ways preserving it in a state of tension and reducingthe force and therefore simplifying the means necessary to impart thework ing impulses thereto, which is a matter of some consequence wherethere are a large number of goods receiving devices in the loom.

Having thus fully described my invention what I claim and Patent is:

1. In combination, with a support and a receiving device journaledtherein and on which to wind the goods, a guide arranged offset from theaxis of said device and around which the goods extends to said device, agoods shifter normally urged against the part of the goods between saiddevice and guide in a direction generally lengthwise of said axis, saidpart normally acting to over come the pressure of said shifter andassume a plane perpendicular to said axis, and means to impartgoods-shifting impulses to said shifter always in the same direction andgenerally lengthwise of said axis, only at one side of said plane andall within the same Zone.

2. In combination, with a support and a receiving device ournaled on asubstantially horizontal axis and on which to wind the goods, a guidebelow said device around which the goods extends to said device, a goodsshifter pivoted on a horizontal axis crossing the first axis andarranged to bear against the part of the goods between said guide anddevice, and means to impart goods-shifting impulses to said shifteralways in the same direction and generally lengthwise of the first axis,only at one side of said plane and all within the same zone.

3. In combination, with a support, and a receiving device journaled soas to project laterally therefrom and on which to wind the goods, aguide below said device around which the goods extends to said device, agoods shifting structure pivoted on a horizontal axis and bearingagainst the part of the 'oods between said device and guide at therelatively inner side thereof, and means to impart shifting impulses tosaid structure always in the same direction as said device projects andonly at the relatirel outer side of a plane perpendicular to said axisand occupied by the guide and all within the same zone.

In testimony whereof I my signature.
